XF 2.0 Blank page because of corrupted language pack

[Jon Diez]

I have recently upgrade to xenforo 2.00 and I have installed a corrupted XML language pack. Or maybe i haven't installed properly... The result is that i have selected the new installed language in the homepage and now i don't have access to the only admin account in my forum (just a blank page)... The other users can access with the previous half-translated language pack...
can I revert my account language to the default?
